Write a balanced equation for the reaction that takes place

Question

24.3cm³ of 0.02M KMnO₄ reacted with 20.0cm³ of an iron(ii)solution

a) given the half ionic equations:

MnO₄^-1 (aq) + 8H ^1+(aq) + 5e gives you Mn^2+ (aq) + 4H2O (L)
Fe^2+ (aq) -2e give you Fe^3+ (aq)

write a balanced equation for the reaction that takes place

b)determine:

i) number of moles of KMnO₄ used

ii) number of moles of iron(ii) used

iii) concentration of iron(ii)solution in moles per litre

please explain detailed, step by step, the way a 17 year old would understand :)
